A particle has centripetal acceleration whenever it's a making a turn of radius R. If the particle is moving at a constant tangential speed v throughout the turn, then the magnitude of centripetal acceleration is
v²/R
If the particle is following a uniformly circular path, then it moves in a circle of radius R and travels a distance equal to its circumference, 2πR. Let T be the time it takes to complete one such loop. Then the entire circle is traversed with speed v = 2πR/T, so that the centripetal acceleration is also given by
v²/R = (2πR/T)²/R = 4π²R/T²
Answer:
The diameter is 0.022m.
Explanation:
The magnetic field
at the center of the coil is given by
(1). 
where
is the magnetic constant,
is the current,
number of coils, and
is the diameter of the coil.
Now, if we call
the length of the wire, then it must be true that
<em>(this says </em>
<em> coil circumferences (</em>
<em>) fit into </em>
<em> )</em>

putting this into equation (1) we get:

solve for 

putting in the numerical values




we get:


The atomic number Z of an element is the number of protons it contains (and in an atom it is equal to the number of electrons). The mass number M is close to the mass of one mol of the substance but it is defined as the number of protons and neutrons in the nucleus of the atom; there, the main mass of the atom is contained. Hence, N=M-Z=74-36=38(since M counts both protons and neutrons while Z only protons). Thus, it has 38 neutrons.
Answer:

Explanation:
As we know that pressure between the cylinder and plunger is increased by 1.59 times
So this will make a net force upwards on the cylinder which is given as

now we will have

Here initial pressure is given as

now new pressure is given as

so we have force on the cylinder given as




now the acceleration is given as



Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
